Application led October/l,11894.v Serial No. 524,893'. (No model.)

Beit known that'LWrLLiAi/r TYNDALE J EN- in the county of York and Province of Ontario, Canada, have'invented a certain new and Improved Golf- Club, of which the following is a specification.

The object of my invention is to devise a golf-club superior in driving power to those ordinarily in use and it consists, essentially, of a club the head of which is constructed preferably of spring-steel, the metal Abeing so rounding a' central space, which preferably has ametal spring or a filling of elastic inastructed indetail substantially as hereinaf-v ter more particularly.described.

Figure l is a perspective view of a head of that form of. golf-club known as a cleek. Fig. is a v erticlglongitudinal section of a driver. Fig. 3 is a cross-section of the same through line a b. Fig. 4 is a plan view ofthe saine. Fig. 5 is a plan view of an alternative form of the same. Fig. `6 isa plan view of the same, showing a metal spring arranged in the center space. i

In the drawings like letters of reference inl: dicate corresponding parts in the various fig nres'. i

A is the head of a golf-club, composed of walls B and C, connected at the ends and in closing a space D.

E is a lling, preferably of vulcanized rubif ber, gatta-perch'a orany suitable elastic ma` club with one resilient side, as shownin. the

terial. n

In the cleek illustrated in Fig. 1 the space D is wedge-shaped, as shown. In the formsy illustrated in Figs. 2 to 6 the space is open both at the 'top and bottom.'

In order to prevent the filling from falling out, it is desirable that the metaiforming thelends oi the space'gD be bulged, as `shown at` a a., or that it be otherwise' suitably shaped to accomplish the'purpose. (See Fig. 2.)

In the form showniin Fig. 6 a metal spring E' is substituted for the elastic filling E. This bears at its center against the front wall B.

stead ofv the iiat spring afcoil-spring bearing against the centers of the'front and rear walls might be used. The metal used lo'r the head l is lpreferably springfsteeh drop-forged or oth erwise made of the desirable shape.

The walls B and Care suiciently thin te L be resilient and t0 give elastically when the ball is struck. Although both Walls are shown of 'the same thickness, a certain measure of utility might be obtained if the front wall only were sufficiently thin to be resilient. The

rear Wa'll C may be curved inwardly, as shown in Fig. 5, in which case a portion of the transverse pressure on the filling E would be convented into a longitudinal strain on the filling Vin the larger ends'of the space.

In all the forms shown by suitably proportioningthe steel walls the elastic iilling or `metalspring might be-dispensed. with.

Although I show my invention applied to only two forms of club, it will of course be y'understood that it is equally as applicable to'all the various forms of 'golf-clubs in use, Whetherof wood or metal.

. Although I mention vulcanized rubber as the preferable material for the 'lling, it being unaffected by ordinary entremes of heat or cold, many other substanceswsuch as vulcanized gutta-percha, sponge rubber, cork,

wood, or, in fact, any elastic or semielastic substance-might be used for the saine purpose. f

By constructing a golf club as above described I am able, with a club of equal or less.-

weight than those ordinarily in use, to obtain greater driving power with the same or less exertion on'the part of the player.

I am aware that it is old'to providevagolf- English Patent No. 3,822 Vof 1893, and to insert a cushion of elastic material ina frame or backing of metal', as illustrated in the Eng l'lish Patent No. 5,741of 1891, and hence make no claim to'such constructicms.- I regardnciyA inventionsas essentially different from either` ICO Y to accomplish this effect.

blow is felt by the rearA and short end Walls.

yIn fact, therear wall may be said to greatly ent wall as quickly tends to resume its inln,

tial position, and it will thus be seen that the resiliency of the rear wall is used as well as that of the front wall and that the rebound is therefore made partly by each resilient wall.

lVhat I claim as my invention is whereby the rear resilient Wall assists in susf taining the front resilient Wall when a blow is delivered and also in giving a rebound, substantially as described.

2. In a golf club, a head having back and front Walls of resilient material, and end walls connecting said resilient back and front walls,

whereby the rear resilient wall assists insus taining the front resilient wall wherL blow is delivered and also in giving a rebound, the said club being open at the top and bottom of `the Walls, substantially as and for the purpose specified.
